在vb数组中求出指定数目的最大值及其下标

在一个一维数组中,如何求出前n个最大值及其下标,请附代码,谢谢

Answer 1

代码如下：
'arr()为你给定的目标数组，n为你指定的前n个最大值，调用例子：
' Dim arr() As Variant
' arr = Array(1, 4, 5, 6, 2, 6, 8, 4, 6, 7)
' PrintPreN arr, 10

Private Sub PrintPreN(arr() As Variant, n As Long)
Dim Brr() As Variant '排序后的数组
dim Crr() As Variant '用来存储下标
Brr = arr
Dim i, j, tmp, tmp1 As Long
ReDim Crr(UBound(arr) + 1)
For i = 0 To UBound(arr)
Crr(i) = i
Next i
For i = 0 To UBound(Brr) - 1
For j = i + 1 To UBound(arr)
If Brr(i) < Brr(j) Then
tmp = Brr(i)
Brr(i) = Brr(j)
Brr(j) = tmp

tmp1 = Crr(i)
Crr(i) = Crr(j)
Crr(j) = tmp1
End If
Next j
Next i

For i = 1 To n
Print "第" & i & "大的数字为：" & Brr(i - 1), "排序前的下标为：" & Crr(i - 1)
Next i
End Sub
